On a cPanel dedicated server, apache server failed to start. So, while checking the apache logs found this:

==> /usr/local/apache/logs/error_log <== [Sat Dec 20 01:12:27 2008] [notice] suEXEC mechanism enabled (wrapper: /usr/local/apache/bin/suexec) [Sat Dec 20 01:12:27 2008] [warn] pid file /usr/local/apache/logs/httpd.pid overwritten -- Unclean shutdown of previous Apache run? [Sat Dec 20 01:12:27 2008] [emerg] (28)No space left on device: Couldn't create accept lock Solution: First of all make sure your server is not out of space. This can be checked with the command: root# df –h Now, to check how many semaphores are currently in use the command is: root# ipcs -s When the apache (httpd) is stopped, to kill the semaphores ID the command is: root# ipcrm –s

To kill all the semaphores ID , you can achieve this by doing it in a for loop, the command is:

root# for semid in `ipcs -s | grep nobody | cut -f2 -d” “`; do ipcrm -s $semid; done

Note: “nobody” is apache user.

Now start apache with the command:

root# service httpd restart

This has fixed the issue for us.

Ghosting The Machine

This is a short but potentially extremely handy guide to ghosting one Linux box to another (or simply making a full backup of a desktop/server). Credit goes to ‘topdog’ for this.

You might have a small office where you customise one desktop just how you like it and need to roll this out to N other PC’s or simply want a backup of a server or desktop to another machine or even to an image file.

The main tool here is netcat which is extremely powerful and has a multitude of other great uses that won’t be covered here.

Target Machine:

** Boot to linux rescue mode with networking (CentOS works fine)

Initiate netcat to listen on port 30 – # nc -l -p | dd of=/dev/sda (assuming the hard drive is sda and not hda):

# nc -l -p 30 | dd of=/dev/sda

Source Machine:

Dump the contents of the disk to the target PC – #dd if=/dev/sda | nc

# dd if=/dev/sda | nc 192.168.0.20 30

Then to check that traffic is flowing, on the source go to another terminal (ALT/F2) and dump the tcp data on the NIC (assuming it’s eth0):

tcpdump -tnli eth0 port 30

If you just want a backup image you could change the above output on the taget to:

# nc -l -p 30 | dd of=mybackup.img

That’s it. Naturally the target PC/disk cannot be smaller than the source:) I hope this saves someone a lot of time.

The DNS was created in 1984 and in 1985 top level domains were defined. The first top level domains were COM, ORG, EDU, GOV, MIL and ccTLD.

In April 1985 cmu.edu, purdue.edu, rice.edu and ucla.edu were the first registered domain names.

The first .gov was css.gov and was registered in June 1985.

The first .org was mitre.org and was registered in July 1985.

Now for the first .com which was registered on March 15 1985 and it was symbolics.com which still happens to be up and running, although not much to look at.

Now for the first 100 registered domains:

Problem not in the awbs irrp module all new domain default on irrp
renewalmode=AUTORENEW

how to disable auto renew all domains on irrp

The commands are listed MANUAL under registrar document (see HOME link in side menu, and look for API SMTP-DIRECT Manual under REGISTRAR DOCUMENTS).

You can do individual domain updates by clicking DOMAINS in the side menu of your web-interface followed by SET RENEWALMODE. Enter the domain name and select the option you want (DEFAULT/AUTO-RENEW, AUTO-DELETE, AUTO-EXPIRE).

You may do mulitple domains using the batch option. Click MISCELLANEOUS in the side menu of the web-interface followed by EXECUTE BATCH and then see steps below;

1) In the command section enter the following:

command = SetDomainRenewalmode
renewalmode = AUTORENEW or AUTOEXPIRE or AUTODELETE

2) In batch parameter enter: domain

3) In the value list enter domain names to be modified. Please remember to list only one domain per line.

4) Hit EXECUTE to process.

There is no renewal reminder feature as this is a reseller account and resellers are expected to keep track of their registered domains. There is a sort feature you can use to see what domains are expiring or need renewal. Please make sure to set RENEWALMODE back to DEFAULT for those domains that you wish to renew otherwise they will still be EXPIRED or DELETED based on what their RENEWALMODE is set at.

HM

There was definitely enough space on the device where the locks are stored (default /usr/local/apache2/logs/). I tried to explicetely different Lockfiles using the LockFile-directive but this did not help. I also tried a non-default AcceptMutex (flock) which then solved the acceptlock-issue and ended in the rewrite_log_lock-issue.

Only reboot of the system helped out of my crisis.

Solution: There were myriads of semaphore-arrays left, owned by my apache-user.

ipcs -s | grep apache

Removing this semaphores immediately solved the problem.


ipcs -s | grep apache | perl -e 'while () { @a=split(/\s+/); print `ipcrm sem $a[1]`}'
